DeSOTO, Texas -- The Rivals250 Underclassmen Challenge presented by Under Armour was the final event of the inaugural Rivals Camp Series. Rivals.com analyst Jason Howell breaks down the top underclassmen without offers.

Hearne started a little slow but once he warmed up, he was among the better interior linemen at the camp. He is already drawing some interest from college coaches and he has a strong frame with little bad weight. While he is a bit raw, the potential is there.

Garnett is on the small side, but he has some wiggle to him. He is an all-purpose guy who can make you miss in a phone booth and a threat at running back and receiver, and you can see the skills for a return man. He was hard on defenders Sunday with his ability to cut without losing speed.

At 6-foot-2 and 205 pounds, Brown is a thick-framed receiver who was hard for defensive backs to get a handle on. He ran precise routes and did a good job of creating separation from defenders and going up and bringing in the reception.

Amanfo is a solidly built outside linebacker at 6-foot, 200 pounds and he was on point as he moved through drills. In one-on-ones, he was able to stick with receivers and was aggressive as he won his fair share of battles.

McPeek caught the eye with his Mohawk hairstyle and his play. He plays tackle, guard and center, but took the majority of his reps at guard on Sunday and showed some nice footwork. He had a quick, strong punch and did a good job of keeping his hands right in the chest of his defender.

Christmon is an aggressive linebacker with great lateral movement. On Sunday in DeSoto, he was physical with receivers out of the backfield but he also showed the ability to stick with them downfield and force incompletions.

At 5-foot-8 and 170 pounds, Strong is not the biggest but he is quick, powerful and decisive. He showed off some fancy footwork in position drills and then when the action moved to one-on-ones, he ran clean routes and showed some nice hands.

Sparks-Brown has a great build and is a versatile weapon out of the backfield. He did not take many one-on-one reps after sustaining an injury, but left quite the impression as he showed off his footwork and burst in position work.

These events can be hard on truly talented big backs, but not Roland Adams. He has a stout build at 6-foot, 191 pounds and showed quick feet and burst and explosion that has made him a standout on offense and special teams for Florence in Alabama.

Booze has the ability to play linebacker or defensive end, but on Sunday he put in his work with the defensive line and showed well. He did a nice job of working his hands and showed some speed off the edge as well as some nice counter moves.
